abstract OO.ui.mixin.FloatableElement

Constructor

new OO.ui.mixin.FloatableElement([config])abstract #

Element that will stick adjacent to a specified container, even when it is inserted elsewhere in the document (for example, in an OO.ui.Window's $overlay).

The elements's position is automatically calculated and maintained when window is resized or the page is scrolled. If you reposition the container manually, you have to call #position to make sure the element is still placed correctly.

As positioning is only possible when both the element and the container are attached to the DOM and visible, it's only done after you call #togglePositioning. You might want to do this inside the #toggle method to display a floating popup, for example.

Parameters:

Name Type Attributes Description
config Object optional

Configuration options

Properties:
Name Type Attributes Default Description
$floatable jQuery optional

Node to position, assigned to #$floatable, omit to use #$element
$floatableContainer jQuery optional

horizontalPosition string optional
 'start'

Where to position $floatable horizontally: 'before': Directly before $floatableContainer, aligning f's end edge with fC's start edge 'after': Directly after $floatableContainer, aligning f's start edge with fC's end edge 'start': Align the start (left in LTR, right in RTL) edge with $floatableContainer's start edge 'end': Align the end (right in LTR, left in RTL) edge with $floatableContainer's end edge 'center': Horizontally align the center with $floatableContainer's center
